My boss drives one of these. He has said there is also a reported problem with the clutches on the csl's, his car is in for the second time to get another clutch, it will be his third within 20000 miles. This is apparently a known fault on the car, it has been reported to BMW who have said they are going to stop changeing clutches under warranty soon untill they have found a fix to why the clutch keeps giving out. Boss has said he thinks it may be a software related issue on the gearbox, with the clutch not adjusting itself as it wears. CSL Man have you had any problems with yours yet?
